The company Graf, located in Rapperswil near Zurich, is one of the leading manufacturers of clothings for flat cards and roller cards. Graf will introduce several innovative solutions at ITMA in Milan.
Flexible clothings are one of the key components in a carding machine. To ensure an evenly high quality of the carding-sliver, they have to be replaced regularly. When the personnel is doing the replacement, the carding machine has to be stopped. To keep these down-times as short as possible, Graf now offers a new flat top system, which can reduce the stoppage by 70 per cent. The so-called EasyTop is used for magnetic flat top clothings. The flat tops, equipped with a steel-backside, are attached securely and precisely with a magnetic fixation. They resist even high carding forces and guarantee for a high reliability of operation.
The replacing of the flat tops is very simple: They can be removed and reattached manually. There is no requirement for additional tools. After placing the EasyTop on the flat bar, the strong magnets automatically assure the correct positioning. The flat top bars are mounted on the carding machine, which can continue the production immediately after adjustment. The reduced stoppage increases the cost-effectiveness. The flat tops do not have to be equalized in a flat workshop, which reduces the costs even further. The EasyTop system can be used together with flat bars with magnetic attachment from all manufacturers. The flat tops are available for working widths of 40´, 51´ and 60´ and setting patterns for all major applications.
